Greetings!

In config file of virtual machine I set "args: -enable-nesting" option.
But when I tried to start I've got "kvm: -enable-nesting: invalid option"...
Whats wrong, maybe I need special pve-qemu-kvm?
 
Hi,
What you must do is set the CPU from the VM on Type "host"
and be sure that KVM hardware visualization is turned on.
That's it.
 
This options was set.

VMconfig

args: -enable-nesting
bootdisk: virtio0
cores: 1
cpu: host
ide2: none,media=cdrom
memory: 3080
name: fosx
net0: virtio=3A:67:9F:C6:5C:F1,bridge=vmbr0

No results, still have an error.... "kvm: -enable-nesting: invalid option"

pve-qemu-kvm 2.1-5 from box
It's strange ! But in binnary file no string with -enable-nesting

strings /usr/bin/kvm |grep nesting
r->nesting > 0

Have any ideas?
 
Where come the -enable-nesting from!
 
Try this:

args: -enable-kvm
bootdisk: virtio0
cores: 1
cpu: host
ide2: none,media=cdrom
memory: 3080
name: fosx
net0: virtio=3A:67:9F:C6:5C:F1,bridge=vmbr0
ostype: l26
smbios1: uuid=91fbb5ec-52d9-4139-a9fd-0f6c79ec52eb

virtio0: local:111/vm-111-disk-1.qcow2,format=qcow2,size=32G
